2. General product information Description The Colima TOR magnetic-activated level switch is designed to control the liquid levels in most industrial applications. The unit comprise of a rigid rod for vertical installation that is used for full automatic management of tanks (including pressurised ones) allowing operations such as starting / stopping of pumps, opening /closing of solenoid valves and activation of alarm systems. - Page 7 Materials Part Material Housing Aluminium Epoxy coated / Stainless steel Terminal board Melamina 4 - 20 mA output converter Plastic 304 / 316L / PVC / PP / PVDF Flange or thread Lowest applicable nominal diameter 50 mm (2") with nominal pressure related to design needs. Tube and wetted parts 316L / PVC / PP / PVDF Float...
- Page 8 Models: TOR A Type recommended for most industrial applications. All wetted parts are made totally of stainless steel. Equipped with reed switches, which allows control of up to six switching points with a single instrument. Equipped with a potentiometer transmitter allowing continuous reading of liquid level.
- Page 9 TOR PC Type indicated for corrosive liquids, such as acids and brines, where the use of stainless steel is not recommended. All wetted parts are made totally of PVC-Polyvinylchloride. Equipped with reed switch contacts, PC allows the control of up to six switching points with a single instrument.
- Page 10 TOR FL (Free Wires) Model FL is designed for naval applications. Float built in stainless steel or BUNA N; other wetted parts built in stainless steel. Model FL can be fitted only with reed switch contacts, with a single tool allows to control up to three fixed switching points.
- Page 11 TOR S Type S is designed for applications in naval bilges to control oily and saline wastewater. It is also serviceable in hardly accessible compartments, where is necessary to detect the presence of liquids. Fittings with reed switch contacts, SPDT or 1 DPDT, to control a single switching point.

- Page 14 4. Contacts Contact characteristics Reed- Switch SPDT or SPST contact Also available DPDT (two SPDT simultaneous) Switching capacity 60 VA 30 W Switching current (I peak) Switching voltage 230 V ~ / 110 V = Maximum number of contacts per instrument The terminal board inside the housing can connect a maximum number of 18 cables.
- Page 15 How to adjust switching point: 1. Disconnect all of the electrical connections. 2. Remove the unit from the tank and lay it carefully on a flat surface. 3. Remove the cover. 4. Disconnect the wires from the terminal board and unscrew the metallic plate located over the terminal board, using the supplied tool.
- Page 16 5. Transmitter Potentiometer transmitter characteristics A potentiometer, a device comprising a printed circuit board on which a reed /resistance chain is welded, is placed inside the float’s vertical guide tube. The total resistance of a known value is measured at the ends of this potentiometer. The float, following the liquid level trend, activates the potentiometer’s reed contact chain through its own magnetic field, locally closing the signal.
- Page 17 6. Disassembling Disassembling Before disassembly of the level switch disconnect or isolate any electricity supply or circuit and depressurize the tank. Warning: do not disassemble the level switch before the tank has been emptied. 6.1.1 Open housing. For E Ex-d housings wait at least five minutes before open. 6.1.2 Disconnect electric circuit cables.
